Abstract:
Pancreas is a unique organ due to its endocrine and exocrine function which plays a pivotal role in the food digestion as well as metabolism of glucose for energy generation. Pancreatic malfunctioning may affect the basal metabolic rate and have significant impact on body weight in the poultry. The present study evaluates the various lesions under different pathological conditions and its correlation with various poultry diseases. An aggregate of 240 samples of pancreas were collected from chickens affected with diseases of viral, bacterial, protozoal, fungal, metabolic, and toxicological origin. The birds under the present study were categorized on the basis on age (0-2 weeks, 2-4 weeks and above 4 weeks) and the diseases were confirmed on the basis of flock history, sign, symptoms and necropsy lesions. The gross lesions observed in the pancreas were bleached, atrophied, congested, deformed and mottled with necrotic foci, however, few lesions were hyperplastic. The gross lesions were more evident for bacterial diseases as compared to viral diseases. The histological lesions observed in the pancreas included interstitial fibrosis, congestion, diffuse pancreatic fat necrosis, individualization of acinar cells distended zymogen granules and thickened capsule. Acinar components were more affected than that of islets of Langerhans. Therefore, it was concluded that pathological alteration in the pancreas of the Vanaraja and Chabro breeds of poultry were more common in metabolic diseases as compared to other infectious diseases.
